14.9 Restarting Your Spa in Cold Weather
If you want to start up your spa after it has sat empty for a time in
freezing temperatures, be aware that the water remaining in certain
sections of the piping may still be frozen. This situation will block water
ow preventing the spa from operating properly and possibly damaging
the equipment. We recommend you consult your dealer for guidance
before attempting to restart your spa under these conditions.
15.0 Water Quality Maintenance
To decrease the risk of contracting a waterborne illness (e.g. an infection,
bacteria or virus) and/or respiratory ailments
, m
aintain water quality
within specied limits. This will enhance your enjoyment and prolong
the life of the hot tub’s equipment. Doing so requires regular attention
because the water chemistry involved is a balance of several factors.
Procrastination in regard to water maintenance will result in poor and
potentially unhealthful conditions for soaking and even damage to your
hot tub investment. For specic guidance on maintaining water quality,
consult your Authorized Jacuzzi dealer who can recommend appropriate
chemical products for sanitizing and maintaining your hot tub.
WARNING: FAILURE TO MAINTAIN WATER QUALITY
WILL:
Increase risk of contracting a waterborne illness (e.g. an •
infection bacteria or virus) and/or respiratory ailments
.
Damage the equipment, components and spa shell, which •
are not covered under the hot tub’s warranty.
!
CAUTION: Never store hot tub chemicals inside the hot tub’s
equipment bay. The equipment bay may reach elevated tempera-
tures, this is where high voltage electronic devices are located. This
area is not intended for storage of any kind.
15.1 pH Control
pH is a measure of relative acidity or alkalinity of water and is measured
on a scale of 0 to 14. The midpoint of 7 is said to be neutral, above which
is alkaline and below which is acidic. In spa water, it is very important
to maintain a slightly alkaline condition of 7.4 to 7.6. Problems become
proportionately severe the further outside of this range the water gets.
A low pH will be corrosive to metals in the spa equipment. A high pH will
cause minerals to deposit on the interior surface (scaling). In addition,
the ability of the sanitation agents to keep the spa clean is severely
affected as the pH moves beyond the ideal range. That is why almost all
spa water test kits contain a measure for pH as well as sanitizer.
